Jason Grant has it pretty close. Your Will can create a testamentary trust upon your death. But you have to stipulate that and all the details, trustees, purpose, beneficiaries, etc. in your will. A trust is a legal entity similar to a corporation so it holds title to your property. That's why there's nothing to probate if you already have a trust in place when you die. If you specify a trust to be created in your Will the probate court will decree it's establishment which basically creates it at that time. And yes, do a NFA trust all by itself, it's just a better idea and NFA trusts are much cheaper that a revocable trust.
